So, looking at the schematic below......I have a few more questions25 turn pot in the filament supply. For the life of me I can't source a 25 turn pot. The 10 turn Bourns 3590 is the closest I can find. Do I need to keep looking for a more sensiti...

To keep with Romy's spirit of sharing his work, I have attached a file of VER 1.0 of the DSET Power Supply. There are quite a few differences to Romy's published schematics but it is basically the same beast. You will notice a lot of power transfor...

Sure, Romy. The commercial product has both midrange and tweeter horns inside the mouth. My plan is to use the bass horn on it's own, as a dedicated bass channel. The plan appeals to me because there are no folds, among other reasons. The expansio...

Hi Romy, Many thanks for replying. I do not want to modify the two drivers. I agree with about all the BS from people selling speakers with TAD drivers. What I want to do is replace the crossover with one of higher grade parts and thereby also elimin...

Chirag, I have some other guys who were asking about the 834P schematic. I just got home and made a picture of my manual with the schematic in it. I do not know if it’s legal. It sort of none-commercial site and I did paid long time ago for my first...

this is the first time I've seen the schematic of the 834p. Explains a lot. I always thought it sounded foggy and rose tinted with limited dynamic range. There seems to be alot of feedback in there. Having said that I've never found any of ...

Romy,
New member around here great website! I have what is probably a silly question about the above EAR schematic. I've been in the planning stages of scratch building a phono stage and have been looking at a few designs and ju...

Thanks Funny I was just reading your thread that has this schematic... interesting stuff....

Measet, I will try to find a photo and the schematic as you requested, but it may be a while before I can locate them. Plus, we are still digging out from Hurricane Irma down here. As I recall, I beefed up the raw D.C. supply and then used an LM317 r...

Hi does anybody have a BiDat schematic? I need it badly, I would be grateful for your help....

Hello to everyone, am new to the sight. Been reading for a while and decided to mod my 834. I've had the unit since '96, purchased new from the local dealer. I have noticed a few differences from the schematic, the 220K load resistors R10 and R110...

Thanks for the comments Romy. Would appreciate pointing out where the schematic is for the 7788 phono preamp or even better your friend´s 7788 mic preamp schematic. I can use the phono stage circuit minus the RIAA as a starter and th...

After much consideration I desired to get my test crossover. I chose when for Velodyne SMS-1 that someone pitched at this site before. The unit has 6, 12, 18, 24, or 48 dB/octave low-pass filters that I need and runs up to 200Hz. I do not think that ...

Finally done! A journey that took a total of 11 years after coming across this forum and seeing the Melquiades posts and schematic. Koshka has a beautiful body and will live on in my SET implementation of a 4 box solution. Here is the left channel po...

Romy, would you explain / help me better understand how you implemented the HP filter in Melquiades?The schematic shows a series cap after the first tube stage (C3 and C4 in the schematic). I think these are the first-order HP filters, correct?Quest...

One ironic thing about the ML2s is the contrast between the fantastic workmanship and the mostly average parts. Of course, the sockets are plain crappy, and I suffered plenty with them until I started using the dielectric grease. I have been too ...

Hi Romy,Minor question with hopefully a simple answer.In the DSET schematic you have a 12.1k resistor in the bias for channels B, C, D and F. I have some nice 12k resistors here (not 12.1k) that I could use in those positions...can you see a problem...

[quote user="anthony"]Hi Romy,So, six channels are now operational in the first DSET. By up I mean the anode voltages on all tubes is about right and the currents are in the ballpark of where they need to be. I am yet to check the DC Offset so hope...
